Abstract
Experiments were conducted to measure the agglutinating antibody response of channel catfish to a particulate and a soluble antigen administered simultaneously by one of three routes. Specific antibody production in response to administration of particulate brucella tube-test antigen via intramuscular injection, oral drench, and topical application peaked at 3 weeks in channel catfish held under identical conditions at 21°C. The humoral antibody response was greater in fish injected with antigen than in the orally or topically exposed channel catfish.
Specific antibody was also produced by the same channel catfish in response to the administration of a soluble ciliary preparation derived from Tetrahymena pyriformis Lwoff. Intramuscular injection of Tetrahymena antigen was the only route that produced detectable levels of circulating antibody as measured by direct agglutination of live T. pyriformis cells. The response to the soluble antigen also peaked at 3 weeks.
Neither antigen elicited detectable agglutinins in cutaneous mucus, regardless of the vaccination method used.
